Application 61ml January 25,1907. Serial No. 354,054.

. To all whom 'it may concern:

lle it'knoivn that I, RUDOLPH DniMEL, a citizen oi the UnitedStates of America, anda resident of Chicago, in

'he erin and State ol' Illinois, have invented ,ii 1- 'u`ewan i'usf improvements in Sola-Beds; of which heiollowing 'is a specification.

` -fllie-neiain. objects ot' this invention are to simplify,

pand seat.

strengthen,andfcheapen the construction of sofa beds 'of Athe type in which the. back and soar are hinged togetherand niovable to different positions onV the supporting base,l' aiid to facilitate-the movement o'l the -liack and seat on the hase.

These objects are accomplished by the device shown in the accompanying drawings,' in which.:

Figure l isma side elevation of a sola bed constructed according to this invention and showing the hack and seat in the horizontal position on the base. FieuQ is a vertical section o f the device `with lthe parts in the saine 'relative position. Fig. 3 is a vertical sect ion of a 'soia bed constructed according to Athis invention and showin Lr the back and seat in their normal position when used :is n sofa or flavenport. Fig. 4 isa vertical section.

partly broken away, on the lines 4-4 of Fig. 2. Fir. 5 is a similar vertical section, showing the two bed scctions pulled forward so as to bring the top ol the back section flush with the back of the base, and showing also in dotted lines tliedifierent, positions el the seat in operating the locking means which connect the back In thedevice shown, the Abox serves as'the supporting base and has its side pieces 2 extending toa greater height than the front 3 and back 4 oi said base. On top of each of the side pieces 2 is secured grooved met-al track 5. l, The back 6 and seat 7 which form the twol bedi sections are. slidinglysupported on the basebetween theraised side;A pieces 2.v `Said sections are supportedV near their-connected ends, by 'the rollers S and S) runlIiingin thelgrooved track 5 at each 'side of the hase.'

Said-`rollers 8 and 9 are attachedto the seat section-and the back.section,'respectively The seat 7 isalso Bnpl ported on the rollers 1,0 vwhich are jouinaled Within .the

front part Otthebase at each side, and bear underlthe i side piece 11 di th'e'seat 7. Both theseat 7A and the back have at each-side an additional end piece l2 so as vto'forin -at each side a recess 13j into which the side ",piece`2 extends.y ,A drop leg-.lll` is pivotedto the inside el each-member `l1 of the seat.7 and .is protected by a .casing formedof the strips l5 and '16 4On the opposite lside o. each',membei1l-is pivoted a roller 17 which bears-against theinsid'e of the side piece 2. Each the members 11, both-on the seat and onthe back is Vprovided on its outer lower endlwitli a beveled guidestrip 18. 'The lower end of the side-piece`l-2 is also beveled at l9 The bevel strip y18 and the.bevel end I 19 ol the side piece l2 prevent theseat or back lfrrnn shifting when lowered from the raisedfposit'ion shownl i, by the dotted lines in Fig. 5 and thus prevent the sides oi the hed-sections from striking upon the tracks 5.; The tivo bed-sections are-hinged together at 20. The4 hinges and locking means are oi an old forni consisting of the plates 2l and 22 which are provided with the locking link 23, the guide 24, pin 25 and pawl The lower forward end of the back G is provided at each side y With a stop 27 which abuts against the block 28 for limiting the forward movement of the be :sections upon the base l, and prevents the saine from being pulled forward far enough to release the seat 7 rom the track 5. vThe operation of thedevice is as follows'. When it is l desired to convert the device into abcd, the seat 7 will he pulled forward from the position shown in Fig. 3, by means oi the strap 3l, and then tilted up to the ,vertical position shown by 111e dotted lines in Fig. 5. This will bring the back G down to the horizontal position, as the sent and bar-k 6 will during such movement remain 'locked' al right :ingles by means of the link 23, :is shown in Fig. 3. To release'tlie link, the seat 7 will be pushed to the inclined position as shown by the dotted lines from `the pin 25 through movement ol the pawl 2G.- The seat 7 may then be turned down to the horizontal posi- 'tion','and the bed-sectionsinay be moved on the hase either lo the middle positions shoivn in Figs. l and 2, or mily be pnllediorward to the position shown inFig. 5. 4In vthat case,1 the drop legs 14 will be pulled down to the vertical position, being released from the spring, .buttons 30. In the position shown in Fig. 5, the base 1 'jmay have its back aga-inst a'wall, and the :back \I may be substantially flush with itliewall.` To reconvert the device into a sofa bed. the seat 7 will be tilted up to @he vertical position shown` by the dotted lines in Fig. 5. At ythis position, the link-.23 Will drop into engagement with the pin 25 and thus lock the two bed-sections together so'tlrat the seat may be tilted'downto the horizontal position, and-the back Will at the same timebe 'raised to'lhevertical position. Tlie'seat may then be pushed back to the position shown inFig. 3.

'The location of the supportsor rollers 8 and 9 at the -adjoining edges of the bed sections and near the axis 20 of theirl hingecon'nection, permits the bedA sections to be readily tilted e'rivs'aidl rollers and provides for considerabl'e leverage in handling.,thesarne-rorn the iront end' at 3l The use Oiav pair olv-rollers 8-and9 at the end oieachiofthe bed sections causes rsaid sections to run smoothly along the track'without any'twisting strain during their .movement roinback to front o the base when all ol said rollers are in contact with the tracks.
